Abstract

PURPOSE: A method for converting contents of a message service depending on terminal information on the wireless Internet is provided to pre-convert the contents of the message service before a receiving terminal requests a message to be transmitted, thereby quickly transmitting the message. CONSTITUTION: A transmitting terminal requests a message service server to receive a message(S200). The message service server receives the message, and transmits an SMS to a receiving terminal so that the receiving terminal knows arrival of the message(S210). Before the receiving terminal requests the message to be received, the message service server converts contents through a contents conversion server, and stores the converted contents(S220). The receiving terminal requests the message service server to receive the message(S230). The message having the converted contents is transmitted to the receiving terminal(S240).

Description

Contents conversion method for terminal dependent messaging service on wireless internet}

The present invention relates to a content conversion method of a message service that depends on terminal information on the wireless Internet. In particular, the present invention relates to a method for transmitting a message faster when a message transmission request is made by a receiver by performing content conversion in advance when the terminal transmits a message depending on the receiving terminal information to another terminal.

In the field of mobile communications, the adoption of high-speed and large-capacity communication systems represented by wide band-cord division multiple access (W-CDMA) is expected in the near future.

The adoption of such a high-speed and high-capacity communication system is expected to further increase the functionality of portable communication terminals such as mobile telephones, especially terminals capable of accessing the Internet, which are currently rapidly spreading.

Specifically, it is possible to easily receive moving image contents such as animation, television images, and digital camera photographed images, or high-resolution photographic or still image contents and high-quality music, which are difficult to realize in current communication methods. It is expected to be possible.

Problems when receiving image content or audio content in a mobile communication terminal are problems due to the lack of power and presence in both video and audio due to the small display screen of the terminal, the small speaker mounted in the terminal, and the lack of loud volume. It is said that.

In addition, the portable communication terminal is simpler than a personal computer, and the number of users is expected to increase. However, it is still insufficient to review a service method of contents that fully utilizes this feature.

On the other hand, the schematic network configuration of the existing content message service includes a transmitting and receiving terminal; A message service server providing a message service; A content conversion server for changing the content transmitted from the transmitting terminal into a format that the receiving terminal can confirm; And it consists of a gateway (Gateway) connecting the sending and receiving terminals and the message service server.

In the existing message service providing according to the above configuration, when a transmitting terminal requests a message transmission to a message service server (S100), the service server receives a message and stores contents, messages, and transmission information transmitted by the transmitting terminal. Send a SMS (Short Message Service) containing a URL that can immediately check the message and the content to the receiving terminal (S110).

At this time, when the receiving terminal requests message confirmation (S120), the message service server delivers the content stored in the content conversion server in consideration of the receiving terminal model, the file format and specification to be converted to the content conversion server, and requests the conversion. (S130).

Then, when the content conversion server properly converts the content and hands it over to the message service server, the message service server lowers the converted content and the message to the receiving terminal (S140).

As described above, the message transmission method between terminals in the conventional wireless Internet environment relies on the content conversion process when the receiving terminal requests message confirmation. Should be.

In addition, if the capacity of the content is large or the conversion algorithm is complicated, not only takes a long conversion time, but also adds a time for dropping the content to the receiving terminal, thereby causing a serious delay problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to perform a content conversion process before a receiving terminal requests message confirmation, so that a corresponding content and message can be confirmed within a shorter time when the receiving side requests message confirmation. The purpose is to provide a method.

As the technical idea for achieving the above object of the present invention

A transmission and reception terminal; A message service server providing a message service; A content conversion server for changing the content transmitted and stored from the transmitting terminal into a format that can be checked by the receiving terminal; And in the wireless Internet-based state that provides a message transmission and reception service having a gateway connecting the transmission and reception terminal and the message service server,

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

2 is a message transmission and reception service system depending on terminal information on the wireless Internet according to the present invention.

Looking at the configuration of the message service network shown in Figure 2, the transmission and reception terminals (10a, 10b); A message service server 30 interworking with the SMS center 35 to provide a message service; A content conversion server 40 for changing the previously stored content into a format that can be checked by the receiving terminal; And it is composed of a gateway (Gateway) 20 for connecting the transmission and reception terminals (10a, 10b) and the message service server (30).

In this case, the gateway 20 performs matching with wireless data service infrastructure (IWF) and transmission control protocol / Internet protocol (TCP / IP), and also performs TCP / IP matching with Internet network and wireless data center (DNS) server. do.

In addition, the content contents in the present invention include moving image contents including animations, television images, digital camera photographed images, or still image contents of high definition photographs or paintings.

Next, the message service flowchart of the present invention shown in FIG. 3 will be described.

First, when the transmitting terminal 10a requests the message service server 30 to receive a message (S200), the message service server 30 receives the message and transmits the content, message, transmission information, etc., transmitted by the transmitting terminal 10a. Save and send a short message service (SMS) containing a URL that can immediately check the message and the content to the receiving terminal (10b) (S210).

The message service server 30 sending the SMS transmits the content stored in the message service server 30 to the content conversion server 40 to the content conversion server 40 in consideration of the receiving terminal model, and requests the conversion.

Here, if the content conversion server 40 converts the content appropriately and handed over to the message service server 30, the content conversion server 40 stores the content in a separate storage space (S220).

Then, when the receiving terminal 10b requests message confirmation (S230), the message service server 30 drops the converted content and the message to the receiving terminal 10b with reference to the transmission information.

At this time, the message service server 30 may delete the content previously converted for various reasons, such as when the disk capacity is not sufficient or when the receiving terminal 10b does not request confirmation of the message for a long time.

If the content conversion server 40 deletes the previously converted content, the receiving terminal 10b requests confirmation of the message, or if the information of the receiving terminal 10b is changed, the content is reconverted and transmitted (S240). ).

As described above, according to the content conversion method of the message service according to the present invention, when a terminal transmits a message depending on the reception terminal information to another terminal in a wireless Internet environment, the reception terminal performs content conversion before requesting the message transmission; It is effective to send a message faster without waiting for conversion time after requesting message transmission from the receiver.

In particular, the effect of the wireless Internet message transmission including a large capacity such as video or high-definition image or time-consuming conversion.
